Hardrock 50 power amplifier with optional ATU unit. 50watt 160m-6m. 1-5watt input. Works as it should just don’t use it anymore. Includes manual, usb cord and two SO239 connectors that I didn’t use, I installed BNC on the build instead but you can change out if you want. Full specs on hardrock website. This is about a year old so it is the later updated PCB boards.
